目前,熔模铸造中常用的几种脱蜡方法皆存在一些缺点。如电炉加热法,周期长,而且由于蜡料受热高度膨胀易损坏模壳;溶剂脱蜡法成本较高,并释放有害气体;湿蒸汽脱蜡法虽较迅速,但成批装卸手工操作较多,不适应机械化连续生产。近来,出现一种新的脱蜡工艺一微波脱蜡。原理是:在涂料成分中加入介电“损耗材料”—碳或石 At present, several dewaxing methods commonly used in investment casting have some disadvantages. Such as electric furnace heating, long cycle, but also due to the high degree of swelling of the wax material is easy to damage the shell; solvent dewaxing high cost and release of harmful gases; wet steam dewaxing method is more rapid, but the batch loading and unloading manual operation more , Do not meet the mechanized continuous production. Recently, a new dewaxing process has emerged - microwave dewaxing. The principle is: Add dielectric “loss material” - carbon or stone to the coating composition
